Vectors.isEqual(v1, v2); Vectors.isEqual(v1, v2, eps=0);
The function call "Vectors.isEqual(v1, v2)
" returns true,
if the two Real vectors v1 and v2 have the same dimensions and
the same elements. Otherwise the function
returns false. Two elements e1 and e2 of the two vectors
are checked on equality by the test "abs(e1-e2) ≤ eps", where "eps"
can be provided as third argument of the function. Default is "eps = 0".
Real v1[3] = {1, 2, 3}; Real v2[4] = {1, 2, 3, 4}; Real v3[3] = {1, 2, 3.0001}; Boolean result; algorithm result := Vectors.isEqual(v1,v2); // = false result := Vectors.isEqual(v1,v3); // = false result := Vectors.isEqual(v1,v1); // = true result := Vectors.isEqual(v1,v3,0.1); // = true
